Simple tape measure scrollbar for a woodshop project I'm working on.
Might be janky on mobile at the moment. Also, scrollbars may be visible on some devices.
Tested on the latest versions of Firefox, Chrome and Edge.

Demo with my [Pageable](https://github.com/Mobius1/Pageable) lib: https://codepen.io/Mobius1/pen/zbzWba which allows fast implementation.

Simple demo of the relativistic effects on a moving spacecraft including relativistic mass, time dilation and length contraction.
Adjust the speed with the slider or use the jump buttons.
NOTE: As we're in the reference frame of the ship, we wouldn't normally see it's length contract (we'd instead see the universe contract), but I left it in for demo purposes.
